Homebrew LPP Breaks When I Try to Show an Image

[BringusStudios]

I'm not really sure what's up with this. Do the .png files need to be in some special format, or am I just doing this wrong?

EDIT: "/assets/question.png" is supposed to be "/question.png" in index.lua.

try "question.png" only

 

[BringusStudios]

try "question.png" only

Oops, meant to change that. It should already be "/question.png". Still wont run, just a black screen.

 

[BringusStudios]

Bump, if I can fix this I can help put an end to GBATemp cancer, I swear!

 

[keanutah]

Try doing something like "System.currentDirectory()../assets/question.png"

 

[BringusStudios]

Try doing something like "System.currentDirectory()../assets/question.png"

That gets me "Error: [string "?"]:2: wrong number of arguments"

 

[Megalegacy98]

question = Screen.loadImage(System.currentDirectory() .. "/assets/question.png")

 

[keanutah]

question = Screen.loadImage(System.currentDirectory() .. "/assets/question.png")

What he said. That's what I meant.

 

[BringusStudios]

question = Screen.loadImage(System.currentDirectory() .. "/assets/question.png")

Nope, still black screen. My text isn't even showing up.

 

[Megalegacy98]

Maybe position it like this?

question = Screen.loadImage("/assets/question.png")
while true do
   Screen.waitVblankStart()
   Screen.refresh()
   Screen.drawImage(400,240,question,TOP_SCREEN)
   Screen.debugPrint(0,0,"Press B to exit",Color.new(255,255,255),BOTTOM_SCREEN)
   Screen.flip()

You have a few different problems in your code. I didn't run this since I'm not on the right computer but give this a shot

question = Screen.loadImage(System.currentDirectory().."/assets/question.png")

while true do
  Screen.waitVblankStart()
  Screen.refresh()

   Screen.drawImage(0,0,question,TOP_SCREEN) -- you want the coordinates to the start x position and the start y position. 0,0 would be the top left corner of the screen
   Screen.debugPrint(0,0,"Press B to exit",Color.new(255,255,255),BOTTOM_SCREEN)

  if Controls.check(Controls.read(),KEY_B) then
  System.exit()
  end

   Screen.flip()
end

Nope and nope... If someone wants to just make a code from scratch that does nothing but display a png I can go off of that.

Have you tried using any of the example lua files that are provided with the download?

img = Screen.loadImage(imageLocation)
while true do
    Screen.waitVblankStart()
    Screen.refresh()
    Screen.clear(TOP_SCREEN)
    --Screen.clear(BOTTOM_SCREEN) <-- if necessary
    Screen.drawImage(0, 0, img, TOP_SCREEN)
    Screen.flip()
end

edit: ehh shit clean() is actually clear()

Yeah but the image one doesn't include "file.bmp"

--------------------- MERGED ---------------------------

img = Screen.loadImage(imageLocation)
while true do
    Screen.waitVblankStart()
    Screen.refresh()
    Screen.clear(TOP_SCREEN)
    --Screen.clear(BOTTOM_SCREEN) <-- if necessary
    Screen.drawImage(0, 0, img, TOP_SCREEN)
    Screen.flip()
end

Nope... this is driving me crazy!

You are clearly doing something very wrong, most likely your image placement.

Can you make a .zip file of everything EXACTLY coded and placed correctly?

 

[keanutah]

So all I did was take the code I placed above and move your question.png into an /assets folder. Works fine in Citra.

Not at home right now. All you should know is that when loading the image, "/img.png" would try to load img.png from the root. System.currentDirectory() returns the directory where the 3dsx is located, therefore System.currentDirectory() .. "/img.png" ends up loading "3ds/<homebrew>/img.png".
Also is your script named "index.lua" and placed next to the lpp 3dsx?

This works perfectly. I know the picture was misplaced in the code, the .zip was missing the assets folder, but the one I was testing was ordered just like this... Oh well, thanks for getting it to work!
